摘　　要：以榆树岭煤矿东翼下5煤层老空积水防治为工程背景,提出矿井地下水“复合勘查+定向探放”的工程技术,其中,矿井地下积水区域复合勘查技术方法包括宏观物探勘查、细观钻探勘查和微观化探勘查三阶段等,长距离定向钻孔精确探放水技术方法包括长距离定向钻孔装备工艺及钻孔布置设计等,并对工程实施效果进行监测评价,总体实现了老空积水的疏排,解决了工作面采掘布置的水害隐患。工程应用表明:实施“复合勘查+定向探放”工程技术共6个月,累计疏放老空水约22.6万m^(3),水压由1.42 MPa下降至0.9 MPa,放水效果良好。Taking the goaf of No.5 lower seam in the east wing of Yushuling Coal Mine as the engineering background for cumulation water prevention and control,the technology of compound prospecting and directional exploration was proposed.The composite exploration technology in underground water cumulation area includes three stages,macroscopic geophysical exploration,mesoscopic drilling exploration and microcosmic exploration.It also involves in long distance directional drilling precision exploration and drainage engineering scheme,covering long distance directional drilling equipment technology and borehole layout design.The implementation effect of the project was monitored and evaluated to drainage the goaf water and solve the hidden water hazard caused during working face mining and layout.According to the engineering practice,during the 6 months implementing the technology of composite prospecting and directional exploration,about 226000 m^(3) goaf water was drained,the water pressure decreased from 1.42 MPa to 0.9 MPa,and the water discharge effect was favorable.
